(config) tfo tcp optimized-send-buffer

To configure a WAE for Traffic Flow Optimization (TFO) optimization with an optimized-side send

buffer, use the tfo tcp optimized-send-buffer global configuration command.

tfo tcp optimized-send-buffer buffer-size

Syntax Description

Defaults 32 KB

Command Modes global configuration

Device Modes application-accelerator

Usage Guidelines This command sets the TCP send buffer size on TFO optimized sockets (the connection between two

peer WAEs). For high Bandwidth Delay Product (BDP) links, you should use a value larger than the

default.

The buffer should be equal to or greater than the BDP. The BDP is equivalent to the bandwidth (in bits

per second)

* latency (in seconds). For example, for a 45-Mbps link with a 150-ms (0.15 sec) round-trip

delay, the BDP is 45

Mbps * 0.15 sec = 6.75 Mb, or 0.844 MB (844 KB). In this case, you could set the

buffer size to 1024

KB.
